This invention relates to machines for the production of chains, mail,ring mesh fab-v ric and the like. It concerns more particularly machinesof the type in-which open;

wire ringsor links carriedon a plurality of supports are taken offsimultaneouslyfrom the lower ends of the saidnsupport-s,inserted inthelinks previously? formed and then i closed. a c

1G il'cccircling to the method of operation of this type of machine fortlIG'PFOdLICtlOH of mesh fabric, links are taken ofl simultaneously froma number of supports correspondingzto the number of rings in the fullwidth of the fabric. Inthismanner a whole row of openlinks may besuspended simultaneously in the r-ow of links previously formed, (cf.German Patent No. 291,245), w

The present invention has as its object certain improvements in this,method of opera tion and in the devices for carrying it intoconstitutes a transferable support,is adapted ac tobe readily'removedfrom the device forming the open links and associated, carryingthe said links, with-magazine supports in the mesh making-machine insuch a manner that the latter supports maybe filled with open linksfromthe former while the machine is in operation. Since the link-formingdevice can turn outopen links much faster than the mesh making machinecan operate, one .or-a few of the former devices is sufficient to sup-.

' ply all the links for a mesh making machine I of-thekind mentionedwith ab out fifty "link supports. V ,A further material improvementaccord- 7 ing :tothis inventionis the employment of pairs of needle-liketools for holding the downwardly suspended fabric in a manner similar tothat in whichthe. said tools have i already beenused'in the production,accord.- ing to the step by stepmethod of manufac- =ture,;rofirings andring-formations (cf.

space which: 15321 11 important drawback obviated in the mesh makingmachine according to {the present invention inwhich there are only thetools for feeding and closing the completed links.

An advantage of the mesh-making machine according tothe presentinvention resides in the possibility of readily adapting it for theproduction of fabric with patterns in dilierent colours. {It-is not onlypossible to :pro-

duce differently coloured longitudinal strips simply by filling thedifferent supports of a single row with different coloured links, but

also to produce anydesired patterns in the following manner I *Two' ormo e rows of link supports are arranged one behind-theother and the feeddeviceffor supplying the links from the lower ends'of the supports tothe points where said 7 links 'are= incorporatedfinflthe' "mesh isaranged t o-Qpera fi h h ends of the rows ofsupports.

The invention may also be readily modi-' 1 fied for the production of arow of chains side by side. g

This modification is arrived-at if-each link removed from the supportsis suspended in a single completed chain link and notkin two. as inthe ae o th rmationqf inglmesh 1O fabric? The result'is a'numberofchains-mar:

For the sake ofsimplicity twenty-one such magazines only are shown, but they may number50 or' 60 depending on the maximum width of mesh fabric or mail to beproduced. The supportss are arranged with their upper ends S free sothat they can be'supare provided 011 each support S. Said pro jectionsare so narrow at their neck parts 8 that the gap in the links K canreadily slide past the same; the thicker portions 8 thereof I of thewire of the links.

are let into suitable grooves in the cross beams C, C and are secured inaddition by means of screws 8 to ensure exact positioning vertically(Figs. 10 and 11). At their upper ends S the supports S are formedprecisely as the lower ends of the supports 3 so thatthe transfersupports 8 may be readily centered thereon by hand and may be mounted securely with respect to two perpendicular axes. The links K aretransferred by their own weight, if necessary with some slightassistance by hand, into their correct position on the supports 5.Vibration by means of hammer blows may also be employed to ensure freefall.

The lower ends 8 of the supports S eX- tend so far through openings (Zin an upper guide plate D in the machine frame that their lower endsurfaces are at a distance from a lower guide plate I) equal to thethickness The openings (Z correspond to the exterior shape of the openlinks K so that the latter can slide freely through them into guidepassages D Suspenslon slides E moving in the space between the guideplates D, D are secured similarly to the teeth of a comb on a slidecarrier E which is guided in the machine frame and is given its movementby eccentrics E I on the shaft B. r

The manner in which the mesh is suspended on the obliquely guided combof needles F is clear from Fig. 15. In the position illustrated in thatfigure an open link K has a movement laterally throughhalf the width ofa ring in order to present, in the correct position, the next openlinksfed forward'by I the suspension slides to the row of ringssuspended on said comb. The feed movement and the lateral movement ofthe combs F,

Referring to Figs. 19 and 20 which illustrate a modification of themachine for the production of mesh fabric in several colours, two rowsof supports S are provided and a locking device for thelinks isfurnished at the lowerjend of each support. *In the arrange}memillusu-ated inFig.120cm end it of a doubleflever H -(lft hand" side)engages against theedgefof'thelower end surface" of the support?
